The influence of the large-scale ocean circulation on Sahel rainfall is elusive because of the shortness of the observational record. We reconstructed the history of eolian and fluvial sedimentation on the continental slope off Senegal during the past 57,000 years. Our data show that abrupt onsets o...

The influence of the large-scale ocean circulation on Sahel rainfall is elusive because of the shortness of the observational record.
